Core Graphics painfully slow in iOS4!

[c0der]

In all my games, I set up an NSTimer that calls [self.view setNeedsDisplay] at a regular frequency. This of course calls DrawRect which I use to update the score, etc displayed on the screen. These routines use Core Graphics.

This has worked perfectly until iOS4. In the simulator, the animations by DrawRect are fast, but in an actual iOS4 device, they are painfully slow. I don't see this problem in earlier versions of iOS.

Has anyone else noticed this problem? I just updated to iOS4.1 and the problem persists.

Help!

Somebody...anybody??? Surely I'm not alone with this one.

I spent several hours last night trying different options, but it's still very slow. Any ideas why iOS4 is so much slower? Does anyone have a solution?

I have the same problem in one of my apps. I was going to rewrite the code for the module in question, but now think based on what you posted, that it may be core graphics.

I just can't imagine why Apple would release an update to the iOS that is slower than the previous one.
